The organic light emitting display device may include: a substrate having a switching device, a first electrode electrically connected to the switching device and having a reflective structure, a pixel defining film disposed on the first electrode and defining a display area and a non-display area, a pixel defining film disposed on the pixel defining An organic light-emitting structure on the film and a second electrode arranged on the organic light-emitting structure. Since the first electrode has a reflective structure such as a recessed structure or a protruding structure, a significantly increased light efficiency can be ensured; and because the opening of the pixel definition film is substantially arc-shaped, the uniformity of the pixel can be improved.
Description
technical field [0001] The invention relates to an organic light emitting display device and a method for manufacturing the organic light emitting display device. In particular, it relates to an organic light emitting display device including an electrode with a reflective structure and a method for manufacturing the organic light emitting display device including an electrode with a reflective structure. Background technique [0002] Generally, among flat-panel display devices, organic light-emitting display devices (OLEDs) have the advantages of fast response speed and low power consumption, and have the advantage of relatively wide viewing angle according to their own light emitting methods, so they are suitable for a variety of electrical appliances and electronic devices in recent years. equipment. Existing organic light emitting display devices have a structure in which an anode and a cathode are sequentially provided on an insulating film covering a thin film transis...
